Feature: 1. Material: ABS environmental protection material, first class production process, excellent corrosion resistance, salt spray resistance, heat resistance and stability. 2. Flexible: The antenna adopts a flexible structure design, which can choose a better angle for the signal, and the side can be turned 90° for higher efficiency. 3. Independent Channel: Faster transmission, reduce co channel interference, strengthen signal gain effect, and improve transmission performance. 4. High Gain: The gain is as high as 6dbi, and the transmission range is large. The more open areas are affected by the environment, the farther the transmission distance is. 5. Wide Range Of Applications: GSM, 2G, 3G, 4G, LET full band network equipment, number machines, routers, advertising machines, vending machines, etc. can be applied. Specification: Item Type: Antenna Material: ABS Model: JB-4G-003 Purpose: Signal Transmission And Gain Working Frequency: 700-2700mhz Antenna Gain: 12dbi Standing Wave Ratio: ≤1.5 Impedance: 50Ω Polarization Method: Vertical Polarization Maximum Power: 50W Antenna Interface: SMA Inner Screw Inner Pin Joint Process: Gold Plated Bandwidth: 100MHZ Working Temperature: -40℃~+85℃ Applicable Equipment: GSM, 2G, 3G, 4G, LET Full Band Network Equipment, Number Taking Machines, Routers, Advertising Machines, Vending Machines, Etc..
